The utility model discloses a power battery connecting component for connecting FFC sampling by using an aluminum terminal, wherein an electric connecting sheet is connected with FFC through the aluminum terminal and samples, so that the problems that the welding point is difficult to fix and the consistency of a welding area is difficult to control due to the fact that an FFC turning wire is required to be bent and welded with the electric connecting sheet in the traditional power battery connecting component for FFC sampling are avoided.
Drawings
Fig. 1 is a schematic diagram of the overall structure of the present utility model.
Fig. 2 is a schematic structural view of an aluminum terminal according to the present utility model.
In the figure: 1. a plastic suction isolation plate; 2. a hot riveting connection structure; 3. an electrical connection piece; 4. an FFC assembly; 41. an aluminum terminal; 41a, an electrical connection pad connection area; 41b, cell expansion extension; 41c, hotbar attachment area.
Detailed Description
The utility model will be described in further detail with reference to the drawings and the detailed description.
As shown in fig. 1, the battery connecting assembly comprises a plastic sucking isolation plate 1, an electric connection sheet 3 and an FFC4;
the vacuum plastic isolation plate 1 provides a position for installing the electric connection sheet 3 and the FFC4, and can play an insulating role. Wherein, the electric connection piece 3 is riveted on the plastic uptake isolation plate 1 through the hot riveting connection structure 2, and the FFC4 is pasted on the plastic uptake isolation plate 1.
Unlike the conventional FFC sampling power battery connection assembly, the novel structure adopts the aluminum terminal 41 to connect the electric connection sheet 3 and the FFC4 for sampling. Specifically, aluminum terminals 41 are arranged on each cell sampling point, namely one aluminum terminal is arranged on one electric connecting sheet.
As shown in fig. 2, the aluminum terminal 41 is divided into three parts, namely, an electric connection sheet connection region 41a, a cell expansion extension region 41b, and a Hotbar connection region 41c.
Wherein the electric connection piece connecting region 41a is connected with the electric connection piece 3 by ultrasonic welding; the Hotbar connection area 41c is soldered to the FFC wire by the Hotbar process so that the sampled signal can be transferred from the electrical connection pad to the FFC assembly via the aluminum terminal for transmission to the power cell management unit.
For the cell expansion problem, each aluminum terminal 41 has a cell expansion extension region 41b in the middle for absorbing the cell expansion amount, and the cell expansion extension region 41b is integrally connected between the electrical connection sheet connection region 41a and the Hotbar connection region 41c. The cell expansion extension area 41b is in an elongated strip shape, the width of the area is narrower than that of the other two areas, and when the cell is expanded, the cell expansion extension area 41b can correspondingly extend to absorb the expansion amount of the cell, so that the condition of inaccurate sampling caused by welding spots is not influenced; support is provided for the durable use of the power battery.
Therefore, for the power battery connecting component for connecting FFC sampling by using the aluminum terminal, one end of the aluminum terminal is connected with the electric connecting piece by utilizing ultrasonic welding, and the other end of the aluminum terminal is connected with the FFC by utilizing the Hotbar process, so that the electric connecting piece is connected with the FFC for sampling, and the problems that the welding point is difficult to fix and the consistency of the welding area is difficult to control due to the fact that the traditional power battery connecting component for sampling FFC needs to bend an FFC to be welded with the electric connecting piece are avoided. And the middle width of the aluminum terminal is narrower, so that the middle of the aluminum terminal can be extended to absorb the expansion amount of the battery cell when the battery cell expands, and the condition that sampling is inaccurate due to welding spots can not be influenced.
By adopting the scheme, the FFC can be connected in the power battery connecting assembly to replace the traditional FPC connecting scheme, which has important significance in shortening the development period and reducing the cost of modules and PACK levels, and is beneficial to subsequent automatic production.
The above embodiments are not intended to limit the present utility model, and the present utility model is not limited to the above examples, but is also intended to be limited to the following claims.
